Blood

Enchant a creature. Enchanted creature gets a
+1/+1 counter.
When enchanting Lungs, next creature to be enchanted with Blood gets +2/+2 counter
instead.
When enchanting Heart, look for another Blood
card in your deck, put it in your hand and
shuffle the deck.
In every crimson drop, the stories of generations flow, binding life's journey in a river of vitality.
